The sum of tax and discount will given by:
(15+7.25)%
=22.25%
Total percentage of the total cost will be:
100+22.25%=122.25%
the selling price of the court will be:
122.25/100×275
=4336.187
The answer is 4336.20
1.Simplify.
-2{x}^{2}-4x+13+12{x}^{2}+2x-25−2x2−4x+13+12x2+2x−25
2.Collect like terms.
(-2{x}^{2}+12{x}^{2})+(-4x+2x)+(13-25)(−2x2+12x2)+(−4x+2x)+(13−25)
3.Simplify.
10{x}^{2}-2x-1210x2−2x−12
It is B because 180 degrees is a straight line and if you take away 63 from it it’s 117
